"""Test file for syntax highlighting of editors.

Meant to cover a wide range of different types of statements and expressions.
Not necessarily sensical or comprehensive (assume that if one exception is
highlighted that all are, for instance).

Highlighting extraneous whitespace at the end of the line is not represented
here as all trailing whitespace is automatically removed from .py files in the
repository.
